[Cocos2d-x]代码段记录

一些零碎的代码，便于以后查找

1.添加动画

 //添加动画帧
 CCAnimation* animation = CCAnimation::create();
 for(int i = ; i< ;i++)
 {
   char imgsName[] = {};
   sprinft(imgsName,”img_%d.png”,i);
   animation->addSpriteFrameWithFileName(imgsName);
 }
 animation->setDelayPerUnit(1.0f);
 animation->setRestoreOriginalFrame(true);
 animation->setLoop(-);
 //使用动画帧创建动画
 CCAnimate* animate = CCAnimate::create(animation);
 this->runAction(animate);

2.替换CCSprite的纹理

setTexture(CCTexture2D)

3.Touch事件处理

bool SoundSprite::ccTouchBegan(cocos2d::CCTouch *touch, cocos2d::CCEvent *event)
{
    CCPoint touchPoint = convertToNodeSpace(touch->getLocation());
    CCRect rect = CCRect(getPositionX() - getContentSize().width * getAnchorPoint().x,
                         getPositionY() - getContentSize().height * getAnchorPoint().y,
                         getContentSize().width, getContentSize().height);
    rect.origin = CCPointZero;
    bool isTouchedIn = rect.containsPoint(touchPoint);
    if (isTouchedIn) {
        CCLog("SoundSprite::ccTouchBegan");
        m_PlaySound = !m_PlaySound;
        this->initWithFile(m_PlaySound?I_FARM_SOUND_ON:I_FARM_SOUND_OFF);
        return true;
    }
    return false;
}
